What does PROBABILITY, STATISTICS AND DISCRETE MATHEMATICS deal with?

Answer 1

Probability, with the chances of an event to be succesful, for example, rolling a dice.
You have six possible values, 1-6, but rolling it just can give you one of the six possible numbers: the probability is 1/6

Statistics, this is about probability results. For example, statistics can show you that 70% of mexico city people owns a tv.

Discrete mathematics deals with integer numbers.
Operations are only with integer values, neither fractional nor decimal values.
Its called discrete because they do not use aproximations to show values.
An example of this are computers who only have two possible values, off equals zero, and on that equals one.
Discrete math is used for control theory and optimization control systems.

Answer 2

Probability is the study of "chance". "How likely is it that I do X and Y happens?" For example: If I draw a card from a standard deck, what is the probability that it has a face on it?

Statistics is usually about trying to measure something in a population based on a sample. For instance, using statistics you might ask what result is a reasonable rate of failure in a brand of light bulbs if the company claims a 5,000 hour mean time-to-failure, and what observed rate of failure is so unreasonable that you decide the company's claim is wrong.

Discrete mathematics can contain some probability and statistics, but it's more generally about the mathematics that gets done without continuous techniques (hence "discrete"). Some matrix arithmetic and applications, and some applications of functions without calculus are what I remember.

Answer 3

ha ha
prob is the part u use to calc the expectation of your exotic options, and statistics is the volitility input, and discrete is the jump/barriers/strike in your underlying....

just kidding....

Answer 4

probabilty... like rolling dice
statistics like informational graphs?
discrete..
